I own a 6'6" M Team Daiwa T, and after fishing it for a couple months I have absolutely no complaints. I don't have any more expensive rods to compare it with, but the rod has plenty of sensitivity. I've been using it with #10 Yo-Zuri Ultra-Soft, and as a plastics rod it does a very good job. I've also used it for throwing paddle-tail swimbaits, cranks, topwaters, spinnerbaits, and even frogs. It handles all of those applications pretty well; admittedly it's a bit on the light side for frogs and it also feels slightly overpowered with big spinnerbaits, but for a medium-power rod that's hardly surprising. Overall, I'd say the TDT is a very good value for the $$, especially when you consider that it comes with a 5-year limited warranty.
As far as durability goes, the TDT should be fine as long as you take care of it. That's one reason why I'd steer clear of rods in Wal Mart: a lot of people handle those rods, and in the process they can get banged around. They might not show any damage, but graphite rods can be compromised without any visible cracks and then break at most inopportune times. I'm sure a lot of people buy rods from Wal Mart that last for a long time, but I'd rather not take the chance.
I've handled the Jupiter rods in Wal Mart, and it feels fairly decent just from handling it. Going solely by how the Jupiter feels without a reel or line, I'd stick with my TDT. I'm not real big on the telescopic handle on the Jupiter (which is strictly personal preference), but the whole rod just doesn't seem quite as nice as the TDT.
The TDT also looks better than the Jupiter.
